What Is a Pennsylvania State Inspection?
A Pennsylvania State Inspection is an annual safety inspection required for most passenger vehicles registered in the state. Many counties, including Montgomery and Chester Counties, also require an emissions inspection to help reduce air pollution.
The inspection is designed to verify that your vehicle is safe to operate and complies with Pennsylvania Department of Transportation (PennDOT) regulations.
Pennsylvania Safety Inspection Checklist
During your inspection, certified technicians examine numerous safety components throughout your vehicle.
